Newb question. Is this car worth it?
 

I want to make this brief for now.

Im thinking of purchasing this car:

http://dallas.craigslist.org/ftw/ctd/1109942828.html

Its a 2003.5 Mazda Speed Protege, but doesnt have ANY of the turbo stuff.

No turbo, MAF, intercooler, intercooler pipping, BOV, etc.

He wasnts $3500 obo.

Anyways, the car is driving NA. Non turbo protege exhaust manifold, etc.
Will it be worth it to buy it, and spend the extra $$ on getting her back where she was?

Im not too familiar with Mazdas. Just looking for a nice daily, but this seems some what of a project.

Whats your imput guys?
